In June, Leaky told you about ITV’s plans to produce a show entitled “50 Greatest Harry Potter Moments.” Fans were invited to vote for their favorite moments from the first seven films via Facebook.

ITV has now announced that the 2-hour show will air tonight at 8 p.m. GMT on ITV1 in the U.K. It will be narrated by actor Robbie Coltrane (Rubeus Hagrid) and feature contributions from other Harry Potter cast members, J.K. Rowling, and celebrity fans such as singer Will Young.

To celebrate the release of the final instalment in the Harry Potter film saga, this special programme counts down the 50 greatest Harry Potter moments. Robbie Coltrane – aka Hagrid – narrates the countdown and looks back at the events which have defined the story of Harry and his friends. From the very first meeting aboard the Hogwarts Express to the death of the mighty Dumbledore, there are numerous scenes that have made Harry Potter an international favourite. Featuring contributions from Daniel Radcliffe, Emma Watson, Rupert Grint, JK Rowling, Julie Walters, Ralph Fiennes, director David Yates and many more, as well as chats with celebrity fans including Will Young and Richard Curtis
